Tuesday afternoon temperature readings the International Bank's thermometer clock read 102 degrees at 3:27, a few seconds later it was 103 degrees, and five minutes after that it had jumped to 104 degrees.

Wednesday morning it did it again. The thermometer went from 92 degrees to 93 in just seconds.

According to the National Weather Service, it's very possible for temperature readings to suddenly jump or drop a couple of degrees. This may be due to what is called the eddies of air.

"That's just representative of these little eddies of air as they go past the sensor. They make the temperature go up or down. We see that even looking at the readings in the airport," said Val MacBlain with the National Weather Service.

Official temperature readings for our region are recorded at the El Paso International Airport. That's where you'll find a thermometer that stands about 6 feet off the ground. The sensor is inside a vented box and there are standards that it must meet, those include shade, be away from buildings, and somewhere with a free flow of air.

"On top of this (box) is a radiation shield. What it does is it keeps the sunlight from shining directly on the sensor, plus it allows air to flow through past the sensor without trapping the heat," said MacBlain.

MacBlain said readings can also vary across town. An East El Paso billboard read 86 degrees at 11:12 a.m., but just a few minutes later in the westside side of town another clock-thermometer read 92 degrees.

Experts said it's hard to tell if a reading is accurate because you have to look at the thermometer's set-up.

Direct sunlight might lead to inaccurate readings. Other factors include the surrounding area, nearby concrete, the color of the ground, and other atmospheric factors might also have an effect.
